AUTOMATlC KEY-CONNECTING MEANS FOR A (IQMBlNED TYPE-WRITER AND ADDl-IR.

Specification of Letters Fatent.

Patented June 11, 1907.

Application filed December 31, 1906. Serial No. 350,180.

which the following is a specification.

This invention relates to a combined typewriting and adding machine, and has for its ob ect to provide simple and ei'hclent means whereby the numeral keys of the typewriter will be automatically connected with the adding mechanism when theprinting point of the machine is presented opposite the adding field; and automatically disconnected when the printing point is presented outside of said field, so that, when the machine is operated to print digits outside of the adding field, the keys will not be burdened by the adding mechanism or its operating connec- 'ject-matter.

tions.

A further object is to provide improved key-operated mechanism for rendering the automatic controlling mechanism inoper ative, so that, when desired, the unrestricted independent operation of the typewriter may be. secured, even when the printing point of the machine is disposed to print in what would otherwise be the adding field.

Other objects subordinate to those stated will appear as the succeeding description of the illustrated embodiment of the invention is developed. v

For the purpose of this disclosure, the elements com rehended by my invention are shown app ied to the Elliott-Fisher billing machine of commerce. This machine includes what is known as a flat platen typewriter equipped with adding mechanism arranged to be operated by the numeral keys to totalize a column of numbers as the number are rinted by the typewriter.

he general organization of the billing ma chine. Mounted to travel longitudinally of the Hat platen. 1 to line space the writing, is a machine frame 2 u on which the carriage 3 travels laterally oi the platen for letter spacing. The 11 per portion oi the carriage is in the form 0 a casing 4 surmounted by letter and numeral keys 5 and 6 the stems 7 of which are connected to key levers 8 fulcrumed in the casing 4 and connected by draw-Wires 9 to downwardly swinging type bars 10. The type bars are t'ulcrumed on a type ring 11 pendent'irom the carriage .cas- The carria e is moved to the right by-the usual prope ling mechanism including spring drums and tapes, not shown, and is controlled by a keyoperated escapement indicated generally at 12. As usualin this ciass of machines, the characters are printed one at a time bythe depressionot thekeys, and'the carriage ad; v'ances step by-smp under the control of the escapement as the keys rise to their normal positions.

The edition The adding mech anism, which is combined with the type .ator is' operated.

writing machine, includes a computing device or register 13 adjustable longitudinally of a guide-bar 14 carried by brackets 15 secured to the main frame 2 upon which, as already stated, the carriage 3 travels. Byits adjustment on the bar 14 the register 13 is located in position for use with reference to a column located at any desired point on the work sheet and is secured in such position by a locking device 16.

The specific character of the computing and registering mechanism is not material, but it embraces, as usual, a series of denominational members, number wheels, or digit carriers 17 exposed at the front of the register and equipped with suitable carrying mechanism whereby, when the value accumulated. upon any wheel reaches the limit of that particular order or denomination, the value so accumulated will be automatically transferred to the wheel of next higher order. The adding mechanism also includes actuating mechanism for theregister 13. This actuating mechanism is mounted on and movable with the carriage 3. Its primary element is in the form of an actuator or mas terwheel 18, advanced laterally into engagement with successive number wheels of "the register by the movement of the carriage, and. rotated a different distance by each numeral key for the purpose of moving particular numeral key from which the actukey is. dep'rfssuhthe digit of corresponding value will be printed on the work sheet in a given denominational,posit1on,,and the number Wheel oi corresponding denomination will be given a inovementoi' corresponding value so-that the-value of the \printed' digit will be added to the. aniountalready accumulated in the register.

ine master wheel OJ. actuator 16 1s fixed to "a comparatively long actuator shaft 19'su1tably supported above the carriage'S and each-* numeral keyis operative-1y connected with the shaft 19 by one of 'a-series-oi operating connections all of which are identical in construction andoperat-ion, except as to a graduated varia on'of the movement transmitted-to the s One of tl'ieseoperating connections is shown.

aft from the. several keys.

in Fig. 1-. This connection includes a ratchet 'wheel 2O fixed to the shaft 1.9 and designed to be engaged by a driving pawl 21 pivoted at one e'nd'of a driving arm or lever mounted to swing loosely on the sh aft 1'9. The oppo-' site end of the lever 22 is geared to the rear end a lever fulcrumed at itsi'ront .end

upon the carriage casing and arranged. in crossing'relation with a lever 24 fulcrmncd at its rear end upon the carriage. The levers 23 and are provided with a loose pivotal connection '25 at their point of intersection Thus, when any numeral.

and from the frontend of the lever 24- depends a link 26 connected to the adjacent- In printing outside of the column or add- .ing field the actuator 18 is out of coinci-' dence with the register 13 and therefore the latter is not operated when a digit is printed. it the connections between the links 26 and the numeral keys 6 were maintained, how ever, the keys when printing digits outside of the adding field would be burdened by the operating mechanism oi the register, wl'iicl'i mechanism would. necessarily be operated each time the key is depressed. This unnecessary burdening oi the numeral keys when printing outside of the column is obviously undesirable, and it is for this reason that the links 26 are arranged to be swung out of engagement with the numeral keys so as to render the latter entirely independent of the register or its operating connections.

In accordance with the present invention,

the several links 26, instead of being con--- nected with the key stems 7, as shown in Fig. 1, are normally held. back out of engage ment with the key stems, as indicated in- .lce'ys with the register operating mechanism when the printing point 0 the typewriter is presented to the adding fiel d. In accordance the register operating mechanism whenever, in the advance of "thecarrlage, the printing point of thetypewriter moves into the addingfield or column'and the actuator or mas- .t'er 'wheel moves to a position opposite. the register. To effect this automatic controlof the;connection, a swinging yoke 28is mounted in suitable bearings at the under side of the cover-plate 4* of the carriage casging 4. This yoke includes a rock shaft 29 lCO 'with'the present invention, the keys are designed to be automatically connected withv provided with radial arms 30 between the ends of which extendsa bar 31. The bar 81 is locatedwithin vertical sl0ts32 in the links 26' and thus serves to guide the links when the latter are r'ecipro'ca'ted by the keys for the purpose of operating .the register. In order to simultaneously connect allof the links 26' with the numeral keys 6 of the typewriter, it

is merely necessary to shift the yoke 28 to the position shown-in Fig. 1 from the norm a]. position of the-yoke illustrated in Fig. 5.

- To facilitate the operation. of the yoke for the purpose stated, the shaft 29 is provided adjacent. to one end of the carriage with a notched .arm 33, see Fig-'5, engaged by a pin 34 projecting laterally from a slide 35 imposed against the under side of the cover- 'lever 40.

seems plate a see Fig. 3, and retained by a headed screw 36 passed through a slot 3'? in the slide and secured to the plate 4. By moving the slide forward from the position shown in Fig. 5, the yoke 28 may be swung to the position indicated in Fig. ,1 to present the links 26 in engagement with the key stems.

Extending inwardly from one side edge of the slide 35 is a recess 38 at the center of the bottom wall of which is a notch 39. See Fig. 10. The recess 38 is designed for the accommodation of one end of a lever il) fuicrumed upon the under side of the cover-piate 4 and having connected thereto a retracting spring 41 which tends to urge the lever in a direction ,to cause the retraction of the slide 35 and the consequent disengagement of the keys. When the lever 40 is urged in the op posite direction by mechanism to be described, for the purpose of moving the slide 35 for ward to cause the engagement of keys, the end of the lever 40 located within the re cess 38 bears against the flange 42 or a swinging abutment 43 of anguiar form, see Figs. 3, 4 and 11. One arm of the abutment is iulcrumed upon a screw is projecting laterally from the slide, and said abutment is yieldingly retained in its normal position, indicated in Fig. 6-, in which position the abutment flange 42, which is disposed transverse to the slide 35, extends into the recess 38 and into engagement with one side edge of the In this normal position of the swinging abutment, the lever so, when swung in a direction to effect the connection of the keys, bears against the abutment flange 42 and thus transmits movement to the slide 35, which, as before stated, carries the abutment. The notch 39 is provided for the accommodation of one end of the flange 42 when the latter is in its elevated or normal position.

Any suitable means for retaining the abutment in the osition indicated in Fig. 5 may be provided, but by preference, the fulcrurned arm of the abutment is provided adjacent to its front end with a spring socket 45 con-' taining a spring 46, which bears against one end of apin 47 projecting downwardl from the slide 35 and into the socket. Fort e purpose of operating the lever 40, the end of the lever farthest from the slide 35-is engaged by the forked end 48 of a bell crank lever 49 fulcrumed upon the under side of the coverplate 4 and having its opposite end forked,

as indicated at 50, for engagement with an arm 51 'cxtehded upwardly from a rock shaft 52 extended through the rear wall of the casing 4 and journaled in a sleeve bearing 53 secured to said wall in any suitable manner. At'the rear end of the shaft 52 is fixed an arm 54 located in rear of the casing, as shown in Figsi 2' and 9, and between this arm and the rear end of the sleeve bearing 53 the sllaft is provided with a. loose cam arm provided at its extremity with a cam 56 projecting laterally from the arm. The arm is provided with a iaterally disposed lug 57 which extends over the arm 54. and serves to compel the arm 5st to swing down when the cam arm 55 is depressed, while permitting the arm 55 to be swung up independently oi; the arm 5%. The relation of the two arms 54: and 55 is adjusted by means oi an adjustment screw 58 passedthrough the arm 54 and bearing against the under side of the lug 57, and th retraction of the loose arm 55 to its normal position after being elevated independently of the arm 54 is eiiected by a retracting spring 59 secured at one end to the arm 55 and at its opposite end to the casing i. it will now be evident that by depressing the arm 55, the consequent depression of the arm 54 will rock the shaft 52 and swing the arm 51 to the right, or to the left when viewing the machine from the rear, as shown in Fig. 2. This movement of the arm 51 will cause the bell crank lever 19 to swing the lever 40 against the resistance of the spring 41 and thus advance the slide 35 to eliect the connection of the keys with the register operating connections.

The depression of the arm 55 to cause the operation just described is effected automaticaily by the advance of the carriage which, at a predetermined point in the carriage movement, will bring the cam 56 at the end of the arm 55 into engagement with a relatively fixed cam plate 60 secured to and extended across the front of the register 13, as shown in Figs. 1 and 18. The ends of the plate 60 are oppositely beveled, as shown, so that, when the carriage is advancing to the right (to the left in '2) the cam will be caused to ride under the cam 60 and thus automatically connect the keys with the adding mechanism, while the 1IT- -VIHGI15 of the carriage in the opposite direction will merely cause the cam 55 to ride up over the plate 60 without effecting any operation of the mechanism other than the idle lifting of the arm 55.

it will be noted that the cam plate 60 is substantially coincident in length with the width of the column or adding field. Therefore, the parts will be automatically operated to connect the keys with the adding mechanism when the actuator 18 moves to a position opposite the register, the parts beingretained in the positions to which they when swung down to anisni is unnecessary, and in that event it is desirable that the automatic mechanism for connecting the keys be rendered inoperative,

so that the keys will not be connected with the register operating mechanism at any time during the carriage movement. 'It is for this reason that I provide the slide 35- with the movable abutineiit43, since it will be obvious that by depressing this abutment to the position shown in Fig. 7,- the abutment flange 42 will be moved down out of the path of the lever 40, so that, when the latter is swung, it will play idly in the recess 38, instead of shifting the slide 35 to cause the connection of the keys.

mechanism inoperative is effected by means of a key lever 61 fulcrumed at 62 upon a bracket 63 secured to the under side of the cover-plate. wardly through a slot in the cover-plate 4 and is formed at its upper end withwhat may be termed a disconnecting key 64 by;

adjacent'to' one; end thereof, into' which the lever is moved laterally and retained after being operatechthe fulcrum 62 of' said lever beingisu'lficiently loose, as shown in Fig. 4,

to permit this engagement of the shoulder,

69 formed by the offset ofthe slot, see position indicated in dotted lines" in Fig'le.

When the lever 61 is in its normal position, as shown in Fig. 6, for instance, it opposes no resistance whatever to the-automaticoperation of the mechanism, because as the slide 35 is operated, the abutment 43 moves'back and.- .forth beneaththe' arm 66 of the lever, but the instant thekeyis'swung back to the position shown in I Fig. 7, the abutment is thrown down out of the path of the lever 40, .and the operative connection between the leverxand the slide 35 is thus brokenj' The lever 61 also serve's to lock theslid e 35 against accidental movement when operated to render the slide inoperative by the automatic-mechanism. T To effect this result the slide 35'is provided with a'lateral extension or shoulder 35, in advance/of which the arm 66 is moved arm is in looking position there is not sufficient play between the shoulder 35 and said arm to permit the slide to move forward far enoughto accidentally connectthekeys with.

It is desirable to provide the machine with an indicator by means of which the operator may tell at' a glance This depressionof the abutment 43 to render the automatic- The lever 61 is extended up- I depress the abutment. 43, it being noted that the upper edge of the arm 66 is of: arcuate form so that whe'nth'e matic slide operating device.

es'asie whether the keys are connected to the adding niechamsm or disconnected therefrom. For

i this purpose attach to the cover-plate e a lower indicator plate 70 bearing suitable indications, as for instance the words" total and add, arranged-one in advance of the other, as shown in Figs. 7, l3. and 14.

Arranged to slide; upon the plate. 7.0 is an upper indicator plate 71 having 'an opening .72 through which'one of the'indications on tli e plate 70 may beviewed, the other i'ndica tion being obscured by the plate.

The upper int'licator'pl'ate 71 moves with the slide 35 and is attached thereto in any suitable manner, as 'for'insta'nceby' a block 73 which extends through the coverlate 4, asshown in Figs Thus when the lide 34 and the disconnecting key 64 are in normal position, the indicator'willdisplay the word total, signifying that the-keys are disconnected, so that numerals may be writtenoutside of the adding fieldor. column without operating any part of the adding mechanism. When, however, the printing point of the moves into the adding field from the left side thereof, and theiactuato'r moves opposite the register, the automatic connecting mechanism will operate in amanner heretofore described to advance the slide 35 and thus con. nect the keys-and adding mechanism, them- 1 dicatorbeing simultaneously operated to obscure the word tota f and to display the word add, indicating that the keys'are connected to the adding mechanism for ad dition; l/Vhen tlie'printing point of the machine moves to the right of thegco'luinn or adding field, the slide and its associated partswill be automatically res-toredto normal pos1- tion,and theindicator will again display the word total, signifyingthat the keys and adding mechanism are again disconnected,

and will fail to connect the keys and adding I mechanism so that the latter will not be operated during the printing of numerals in what would otherwise be the adding field.

p It will thus be seen that while the inven tion contemplates the automatic connection of the keys and adding mechanism when the adding field is reached, it also embraces means, whereby the automatic key connectmg mechanism may be placed entirely out of action to permit the unrestricted independent use of the typewriter in printing entirely across the sheet, including the adding field. Obviously however, other indications might be substituted for the words total and faddf as for instance the words -disconnected and connected, signifying that the keys are disconnected from or connected to the operating connections of the register. It is also immaterial whether the indications are displayed on a separate indicator plate or whether they are imprinted or otherwise produced directly upon the cover-plate of the carriage, the separate plate being preferable for the equipment of machines already in use, with the mechanism embodying the present invention. 7

p In conclusion, attention is directed to Pat ent No. 573,868, to R. J. Fisher, in which the Elliott-Fisher typewriter here shown is exemplified, and to Patent No. 829,971 to Laanke and Smith, to which reference is made or a more complete disclosure of the register operating connections than has been deemed necessary for the purpose of this description.
